METHOD AND APPARATUS FOR TESTING AFCI DEVICE FOR SERIES ARC DETECTION

Testing an AFCI device includes providing an AFCI device to be tested and a load, wherein the AFCI device and the load form an electrical circuit, applying AC power to the AFCI device, generating a high frequency broadband noise signal, amplifying the high frequency broadband noise signal, modulating the amplified high frequency noise signal with a signal synchronized to the load current or load voltage to provide synchronized high frequency broadband noise bursts, coupling the noise bursts into the electrical circuit to simulate series arcing signals, determining if the AFCI device opens the electrical circuit within a predetermined amount of time, indicating the AFCI device has passed the test if the AFCI opens the electrical circuit within the predetermined amount of time, and indicating the AFCI device has failed the test if not.
